RE: Why does running an NST on an async gap kill it?

I believe there are MANY safety gaps out there that are set not to the
maximum NST voltage, but to whatever is necessary to keep them from
firing. And, Terry's filter spec's MOV's for a 15kV NST. If one uses a
lower voltage NST and builds things verbatim without considering if the
design needs to be modified, then a higher than rated voltage can be
